Abstract
GMRES(m),the restarted GMRES method,is popular for solving large sparse nonsymmetric linear systems.However,it is possible to show that the restarted GMRES method may not converge,i.e.be stationary.To remedy this difficulty,a modified restarted minimum residual algorithm,MGMRES(m),is discussed in this paper.
